Extraordinary transmission characteristics of subwavelength nanoholes with rectangular lattice
Çetin, Arif E.; Drsata, Martin; Ekşioğlu, Yasa; Petracek, Jiri (Springer, 2017)We investigate the extraordinary optical transmission (EOT) properties of nanohole arrays with a rectangular lattice for label-free refractive index sensing applications. We show that the deviation within the periodicities ... -
Metamaterial solar absorber based on TiN/TiO2 multilayer taper structure
M-Ramzi, Mustafa Imad; Ekşioğlu, Yasa; Durmaz, Habibe (Springer, 2023)The increasing demand for renewable energy has increased in the last decade due to climate change resulting from conventional energy and solar cells become popular. The perfect absorption in solar cells can be achieved ... -
Multi-band plasmonic platform utilizing UT-shaped graphene antenna arrays
Ekşioğlu, Yasa; Çetin, Arif E.; Durmaz, Habibe (Springer, 2018)In this work, we introduce a plasmonic platform based on UT-shaped graphene antenna arrays. The proposed multi-resonant platform shows three different resonances, which can be independently tuned. The physical origin of ... -
Sub-diffraction focusing of light by aperiodic masks
Mostafavi, Seyeddyako; Nutku, Ferhat; Ekşioğlu, Yasa (Taylor and Francis Ltd., 2022)Diffraction of a spherical wave through various types of 2D aperiodic hollow masks is investigated computationally. Unlike a periodic transmissive grating, an aperiodic hollow mask can focus light into a hotspot with ...
